Is something wrong with using buffer-file-name? You could create
compile-command by using 'eval', which can accept Emacs functions.

This is the third time you've reported this.
You can avoid this by checking
https://debbugs.gnu.org/cgi/pkgreport.cgi?submitter=jidanni%40jidanni.org

Indeed, so I don't think there's anything here to be fixed. Closing.

(info "(emacs) Specifying File Variables")
(info "(emacs) Safe File Variables")
Should say how to do
http://permalink.gmane.org/gmane.emacs.bugs/8844
correctly, and why there IS NO WAY to specify the current filename,
without a big hassle, even though there is just as much risk as if one
hardwired it into the file.

eval needs to be whitelisted as a safe local variable, creating a security hole.

How about this instead:
before-hack-local-variables-hook is a variable defined in `files.el'.
Its value is (c-before-hack-hook)
This variable may be risky if used as a file-local variable.
Probably introduced at or before Emacs version 23.1.
Documentation:
Normal hook run before setting file-local variables.
It is called after checking for unsafe/risky variables and
setting `file-local-variables-alist', and before applying the
variables stored in `file-local-variables-alist'. A hook
function is allowed to change the contents of this alist.
This hook is called only if there is at least one file-local
variable to set.

All I know is you need to add a paragraph explaining whatever workaround
recipe that is to (info "(emacs) Specifying File Variables"):
"You can even refer to the current file name using local variables!

Not really, because itʼs not restricted to just that, you can do whatever
you want in the hook.

Whatever you are proposing is too complex.
@CURRENT_FILE@ should just refer to the current file, no hacks needed.

You propose @CURRENT_FILE@, someone else will prefer $..$, someone
else again will want a different set of variables available. This is
why the 'eval' functionality exists, which you donʼt want to use,
hence the proposal to use the hook.

OK, please post what the INFO page would say
(easy instructions that even I could follow)
and I'll give it a spin. Any how about just
(setq current-file-local-variable "$CUR_FIL$")
for .emacs...
